4Maxsurf中新船建模与型线设计4.1新船建模与型线设计型线设计原则：保证良好的航海性能，考虑船体结构的合理性和工艺性，考虑总布置的要求，满足型线设计精度，外观造型。首先在Maxsurf中用SizeSurface按一定比例放大母型船船模，形成初步新船船模。然后根据建成的母型船的船体模型以及之前所得的新船主尺度，在Maxsurf的Data菜单中的ParametricTransformation功能，锁定新船的部分参数Cb，LWL,B,D进行改造，此功能是引用型线改造中的Lackenby法，可同时修改Cp、lp、XB，见图4-1。Lackenby法的优点是：可灵活地按需要来改变面机曲线的要素，但计算较复杂，需要编制程序，在计算机上进行运算和改造。新船船模见图4-2；新船横剖面面积曲线见图4-3；新船型线图见图4-4，图4-5，详细图纸见附录B图4-1Lackenby法型线设计图图4-2新船模型图4-3新船横剖面面积曲线4.2新船船模的型线三向光顺分别取横剖面，纵剖面，水线面上的曲度最大的曲线,观察曲率棒是否光顺来检验一下型线设计三向光顺性，见图4-1、图4-2。图4-1新船横剖面的三向光顺检验图4-2新船纵剖面的三向光顺检验4.3新船船模的性能参数新船在Maxsurf建好模型后所得的静水力计算见表4-1。表4-1静水力计算项目数值单位排水量22559t排水体积22009.207m^3船舯吃水8.420m吃水8.420m水线长146.112m水线处最大宽度23.147m湿面积4850.584m^2水线面面积192.227m^2菱形系数2986.487m^2方形系数0.784中横剖面系数0.773水线面系数0.987浮心距零点纵向位置-69.967fromzeropt.漂心距零点纵向位置-74.176fromzeropt.浮心垂向高度4.41m初稳心半径5.354m纵稳心半径197.967m横稳性高9.767m纵稳性高202.380m5新船快速性的初步计算5.1设计主要要求设计航速为15节。5.2Resistance阻力计算依据及计算结果根据MaxsurfResistance使用说明及新船要求的航速航区等条件，可以看出用Series60计算出来的结果都在允许范围内，以下是对比过程。方形系数要求：0.6<Cb<0.8新船Cb=0.773，因此符合要求。要求：5.5<<8.5新船=6.23，因此符合要求。要求：2.5<<3.5新船=2.74，因此符合要求。由此可知，用Series60方法计算新船快速性。在航速为15kn时功率为4932kW（）81%：图5-1航速与主机功率关系表5-1新船部分快速性计算表项目航速（kn）阻力（KN）功率（KW）113.125344.42871.187213.500370.03172.623313.875400.83531.957414.250434.63932.902514.625471.04375.266615.000517.74932.216计算结果得出航速在15节的时候船收到的阻力为517kN，主机功率为4932kW下就是关系曲线图5-2、图5-3和计算表5-1。图5-2功率与航速的关系曲线图图5-3阻力与航速的关系曲线图由以上图5-2图5-3表5-1可以看出，当新船的航速达到15节时，将会受到516.03kN大小的阻力，主机功率的需求为4916kW。与之前考虑到功率储备时的主机功率5440kw相近，所以新船主机功率是满足任务设计书里面的快速性要求。
